February 2, 2012: Blobs in the Night | Feb. 1 | Feb. 3 | 2011 | FOTD Home |
Fractal visionaries and enthusiasts:
Today's
image is a
blast from the past, a slight tweaking of an image that appeared
several years ago. The image was created by the
MandelbrotMix3
formula, which mixes four powers of Z on each iteration instead of the
two that the MandAutoCritInZ formula mixes. The big drawback
of
the MandelbrotMix3 formula is that a critical value of initial Z must
be found by hand, and even using the graphic method, which can be done
with Fractint, the task is laborious.
The real(p5) parameter is the critical value of today's iterated
expression.
In today's image, 0.4 parts of Z^(1.8), two parts of Z^(-0.8), one
negative part of straight Z and two parts of Z^(0.8) are all combined
before (1/C) is added. This strange mixture draws a parent
fractal that resembles a ragged figure 8 with a broad stripe of chaos
running horizontally through it and an obvious Mandeloid in the center
of the stripe. To find today's image however, I checked the
jagged southern edge of the figure 8, where the minibrots are plentiful.
Much of the blob-like effect was achieved by rendering the image with
the inside set to 'bof60'. The rating of 8-1/2 is held back
because the image is a recycled one. The name "Blobs in the
Night" came to mind when the image reminded me of one of my favorite
junky old sci-fi movies, 'The Blob'.
With so much stuff to calculate on each iteration, the image takes
4-1/4 minutes to finish, which is a bit slow by FOTD
standards.
But once again the web sites ride to the rescue.
Too many clouds filled the sky here at Fractal Central today, which
made the day less than perfect. The temperature of 43F +6C
was
mild enough, but the lack of sunshine kept the fractal cats in sulky
moods. The humans, FL and I, had an uneventful routine
day.
I know it's dull to write about, but that's how everyday life on earth
goes.
The next FOTD will be posted in 24 hours. Until then, take
care,
and it appears that every weather event that happens turns into a sign
of global warming. My opinion is that the world is indeed
slowly
growing warmer, but we can do nothing about it, so let's stop trying to
pass more laws that will surely fail, and use our resources to prepare
for the warmer environment that is sure to come. It will not
be
nearly as catastrophic as the doomsday prophets with political agendas
would have us believe. (The ever-increasing numbers of humans
are
the real problem.)
